This didn't work before because the elaborate type punning scheme was
deactivated by including proj.h. Now we use the type punning from the
new API header and build our own.
This change is required for #674.

Helmert improvements
|
|
|
|
|

Prefixing with t_ is more consistent with the existing parameters
in PROJ, such as x_0 and friends. t_epoch and t_obs is already used
in PJ_deformation. Now users can expect consistency across
time-varying transformations.

Update documentation on geodesics
|
|
* replace SVG figure by PNG version,
* rewrite maths using :math:,
* put references in the main reference section,
* reformat references for consistency,
* put references in alphabetical order,
* use USGS URL for Snyder (1987).

Remove the last remains of the internal selftest

same file (#687)
Fix bad typedef that surfaces when including proj.h and proj_api.h in the same file
|
|
|
|
Free formatting of PROJ key=value pairs
|
|
use full error code checking on failure in more_builtins.gie
|
|
|
|
|
|
* Enable selective debug printout through negative PROJ_DEBUG values
|
|
Add GDA2020 tests, and correct the PJ_helmert bug they revealed
|
|
calculations with something more helpful to the beginning user.

Decisions regarding the size of certain types are always made at
compile time, hence this is where the assertion should take place.
If the assertions fail, there is now a compiler error.
|
|
* gie support for builtin errcodes, and other improvements
* allow lower case error constants

Increase the focus on PJ_COORD as primary datatype: Eliminate use of PJ_TRIPLET etc.
Trim proj.h by removing material that has become unnecessary.
Improve constness
Make proj_factors work in proj.h space, by providing a trimmed down PJ_FACTORS (which even has more meaningful field names)

Improve error messaging for cct and gie, and do some clean ups in the ellipsoid handling - partially to squash bugs, partially to improve naming consistency which, in turn, improves the readability of the ellipsoid handling code.
Renamed functions:
pj_inherit_ellipsoid_defs has been renamed pj_inherit_ellipsoid_def, while pj_calc_ellps_params has been renamed pj_calc_ellipsoid_params.
The code in get_opt (part of pj_init.c), which handles whether or not an ellipsoid definition should be dragged in from proj_def.dat, has been rewritten. I suspect this was buggy beforehand, and at least the new code is easier to follow (although it may be slightly slower, which is not really a problem as it sits in the setup code, and hence is executed only once).

Central conic projection implemented as 'ccon'.
|
|
* Replace pj_ell_set with reimplementation supporting ellipsoid inheritance
* remove unreachable code from pj_ell_set.c
* Swap steps, so ellps args are read first, in accordance with historical behaviour
* Add ellipsoid tests to CI targets
* Reduce some optimistic tolerances
OS/X appears to have a slightly off float handling, resulting in differences at the nanometer level. Switching to 10 nm.

Switch pj_factors to use proj_geoc_lat

These were accidentally dropped during PR #669
|
|
* Introduce geodetic-geocentric conversions, as PJ_xxx style conversion step and as API entry points
* minor improvements and minor bug squashing

Give definition and def'n line no. in "Invalid operation" message
|
|
A year or so ago, @micahcochran put quite some effort into rationalizing the PI usage in PROJ.4, by ensuring that a useful number of M_PI related constants were defined in projects.h.
But apparently adjlon.c was left behind still using its own set of definitions - perhaps because it bends the values slightly, to avoid unwanted sign switching near the date line.
In this PR the "bending trick" is reimplemented using the rationalized M_PI constants only.
|
|
* Support numerical factors only
* Make sure h positive. Improve some comments
* Let pole overshoot check have effect even for geocentric latitudes
* Factor-typological constants, now all returning false, for backwards compatibility
|
|
|
|
* Removed remaining traces of the builtin selftest system. Moved all functionality to test/gie
* Updated Appveyor and Travis build scripts
* Another appveyor script update
|
|
* Poder dual autochecking implementation
* Debugging aid: Improvements in PJ_vgridshift.c and gie.c
* Most likely, the bugbeing tripped is in the gridshift code, so. uncomment suspicious lines in deformation.gie and merge this to support the debugging effort
